Question

The figure shows the acceleration-time graph of a particle. Which of the following represents the corresponding velocity-time graph? ( consider initial velocity is zero )

• A.
• B.
• C.
• D.

Answer 1

Answer: (B)

Since acceleration is constant, therefore there is uniform increase in velocity. So, the $v-t$ graph is a straight line slopping upward to the right. When acceleration becomes zero, velocity is constant. So $v-t$ graph is a straight line parallel to the time-axis in that duration. Again there is a constant acceleration so velocity of particle will increase linearly.
